Functions | |
int | main (void) |
Main function. Execution starts here. More... | |
void | main_cdc_disable (uint8_t port) |
Closes the communication port This is called by CDC interface when USB Host disable it. More... | |
bool | main_cdc_enable (uint8_t port) |
Called by CDC interface Callback running when USB Host enable CDC interface. More... | |
void | main_cdc_set_dtr (uint8_t port, bool b_enable) |
Save new DTR state to change led behavior. The DTR notify that the terminal have open or close the communication port. More... | |
void | main_resume_action (void) |
Turn on a led to notify active mode Called when the USB line is resumed from the suspend state. More... | |
void | main_sof_action (void) |
Manages the leds behaviors Called when a start of frame is received on USB line each 1ms. More... | |
void | main_suspend_action (void) |
Enters the application in low power mode Callback called when USB host sets USB line in suspend state. More... | |
